alternative browser to IE on a Terminal Server - Firefox

We have an old Windows 2000 Terminal Server which is not about to be upgraded for a while. We are running into issues with the old IE on it - which can't be upgraded - working with certain Web sites. We don't want to install another browser at this point. What we want is to use something like Firefox or whatever works as a browser to create links to the sites that can't be reached but that's it - they can't use it for any other sites. So for example the user would see a link that says - www.ie-inaccessiblesite1.com. They click on it and go to that site but that's it - they can't browse any more sites, can't really run the full version of the browser.

How, if possible, could we do this? We are indifferent as to the browser - Firefox, Chrome, etc.

I did, however, Google for it and it doesn't address what I want - it seems to restrict people in Firefox from getting to the desktop e.g. Windows. That's not the issue. The desktop is locked down enough and users need to access it - they are internal users who need a desktop. What I need are links on the desktops to Web sites that just open to a single Web site - people can't get the full browser. So people get the full desktop but not the full browser. If I have missed something in my reading/interpreting please point out documentation where I might accomplish what I am looking for.

Thanks for pointing it out. I had read too fast. When I saw content filtering I thought it worked the reverse - sites that could be blocked - usually what I associate with content filtering - versus controlling what specific sites people can go to which is what I believe this does. Is that how you read it as well? I can have only one or two sites that are accessible as opposed to denying access to site A and Site B, etc

Hello
I think you can easily get your result using a PAC file in Firefox. A PAC is a Proxy AutoConfiguration file. It's a script that you can customize according to your need and it's very suitable for situations like this. For example you can write a PAC file that only allows one on two websites and anything else.

You can start from here, but you can find a lot of infos using Google.

There's little problem to consider anyway: your users could easily remove the setting for the pac file in Firefox. To prevent this the main ways are using a proxy (that could create a non-sense situation) or a firewall. Supposing that you are not using a Proxy (in such a case your question wouldn't be here) probably you are using a central firewall. In that case you could somehow limit connections from firefox forcing the use of the PAC file, but there's some work to do for this, and I can't assure that it's possible in your environment. Maybe there's an addons that can prevent the users to change the proxy setting in FF but I don't remember at the moment (I doubt, anyway)
